It is a layered fabrication technology developed by
Dr. Behrokh Khoshnevis of the University of Southern California. Contour
Crafting technology has great potential for automating the construction of
whole structures as well as sub-components. It involves a 3D printing process
which reduces the energy use and emissions. It is made up of robotic arms and extrusion nozzles, a
computer-controlled gantry system moves the nozzle back and forth, squeezing
out layers of concrete or other material to fabricate a form. The ultimate goal
is to print a house in a day while drastically reducing material and energy
consumption.
It can construct a single house or a colony of houses, each with possibly a
different design, automatically in a single run, embedded in each house all the
conduits for electrical, plumbing and air-conditioning. The potential
applications of this technology are far reaching including but not limited to
applications in emergency, low-income, and commercial housing. Contour Crafting
can help reduce the cost of commercial construction because it
promises to eliminate waste of construction materials.
